Pfizer Inc. CEO Albert Bourla said people receiving Covid-19 vaccines are likely to need booster shots within a year after that and then annual vaccinations to maintain protection against the virus. what evolves.
“Variants will play a key role. It is extremely important to suppress the group of people who may be susceptible to the virus, “said Mr. Bourla during a virtual event hosted by CVS Health Corp., which aired on Thursday but was recorded on April 1.
“There are vaccines like polio where a single dose is enough,” Mr Bourla said. “And there are vaccines like the flu you need every year. Covid virus is more like the flu virus than the polio virus. ”
More research is needed to confirm the need for annual booster photos, he said. But he added that the need probably arose from research so far.
The chief executive’s comments come as the US and other countries struggle to vaccinate as many people as possible and try to stay ahead of any options that could evade the shootings.
